When you said specialization: Does it mean you don’t believe in the myth of “Full-Stack” developer?

Not necessarily. It’s more about how it’s applied and then marketed then the languages you know. I build membership sites. That’s how I market myself. In that, I use most of the “stack”… I’d just never market my services using the words “full stack”.

Also, marketing yourself as a freelancer is much different than getting hired by a company. I would use “full stack” when looking to get hired because companies hiring developers DO know what that phrase means.

Once you have this done then you would write your PHP script to handle the resulting array. You could serialize it. Depending on your application that might be sufficient.
